litedown 0.5

• Added a wizard in roam() to create new .Rmd/.md/.R files with selected HTML features.

• Added a new engine embed to embed text files via a code chunk.

• Changed the meaning of the chunk option order: previously, higher values indicate earlier execution; now higher values indicate later execution. This is a breaking change, but the new meaning should feel more natural. For example, order = i means to execute the chunk in the i-th step, and order = i - 1.5 means to move the chunk back 1.5 step in the queue so it will be executed earlier than its previous chunk. See https://yihui.org/litedown/#sec:option-order for details.

• Shortened the output format names litedown::html_format to html, and litedown::latex_format to latex. The names litedown::* can still be used if you like.

• Added options dollar, signif, and power to format numbers from inline code. See https://yihui.org/litedown/#sec:inline-code for details.

• When embedding SVG images in HTML output, embed their raw XML content instead of base64 encoding them.

• Empty table headers are removed in HTML output (they may be generated from data frames or matrices without column names).

• Added support for the chunk option collapse = TRUE (thanks, @J-Moravec, #40).

• Added support for the chunk option fig.dim, which is a shortcut for fig.width and fig.height.

• Added a new function vest() as another way to add CSS/JS assets to HTML output.

• Provided templates and a Github action yihui/litedown/site to build package websites. See https://yihui.org/litedown/#sec:pkg-site for details.

• Added an argument examples to pkg_manual() to run examples and show their output (thanks, @TimTaylor, #54).

• Fixed a bug that the default CSS wouldn't be added when a math expression exists on the page (thanks, @calvinw, #61).

• Fixed a bug that cross-references to other chapters of a book could not be resolved when previewing a single chapter.

• Fixed a bug that the file navigation by line numbers on code blocks stopped working in litedown::roam() due to yihui/lite.js@5e06d19.

• Fixed a bug that R code blocks could not be embedded when using prism.js for syntax highlighting (thanks, @TimTaylor, #53).

• pkg_manual() will point out the name of the problematic Rd file when the Rd file fails to convert to HTML (thanks, @BSchamberger).

• Dropped knitr and rmarkdown from the Suggests field in DESCRIPTION. Previously, litedown allowed rmarkdown::render() to use the output formats litedown::html_format and litedown::latex_format. Now rmarkdown::render() is no longer supported, and litedown::fuse() must be used instead.
